Acoustic Inversion for Uncertainty Reduction in Reynolds-Averaged Navier–Stokes-Based Jet Noise Prediction

“…Inferring the noise source information from noise measurements is common in the acoustic community. For instance, the acoustic noise data have been used for localization of the noise source [37,38], detection of the underwater environment [39,40], and inversion of wall pressure [41,42]. Besides, inferring optimal parameters in a noise model [43,44] from noise data was also investigated.…”
